Serine

SERINE is a nonessential amino acid derived from glycine, and contributes to the formation of cystine from homocysteine. Serine has sugar-producing qualities, and is very reactive in the body. It is highly concentrated in all cell membranes, aiding in the production of immunoglobulins and antibodies.

The metabolism of serine leads to such important products as ethanolamine, choline, phospholipids, and sarcosine. These products are all essential to form neurotransmitters and to stabalize cell membranes. Serine is also essential for proper metabolism of fats and fatty acids, muscle growth, and a healthy immune system.

The downside of serine is that its levels are high in such poor quality foods as luncheon meats and sausage. High serine levels have been found in psychotic patients and those with elevated blood pressures and cerebral allergies. The main use for serine is in cosmetics, where it is added as a natural moistening agent.

Other names for serine include: SER, amino acid S, and 2-amino-3-hydroxy-propanoic acid.
